Ugetsu (雨月物語, Ugetsu Monogatari, lit. "Rain-moon tales") is a 1953 Japanese period fantasy film directed by Kenji Mizoguchi starring Masayuki Mori and Machiko Kyō. It is based on the stories "The House in the Thicket" and "The Lust of the White Serpent" from Ueda Akinari's 1776 book Ugetsu Monogatari, combining elements of the jidaigeki (period drama) genre with a ghost story.
Drawing from Ueda's tales, the film is set in Japan's civil war–torn Azuchi–Momoyama period (1568–1600). In a small rural community, a potter leaves his wife and young son behind to make money selling pottery and ends up being seduced by a spirit that makes him forget all about his family.
